[0003] Currently, most methods for separating ferrous metals from shredded scrap car bodies use magnetic separation technology. However, shredded scrap car materials may contain debris such as ropes and plastic films, which can easily entangle the equipment, causing blockages and affecting separation efficiency and stability. To address these issues, we propose an eddy current separator for shredded scrap car materials. Summary of the Invention

When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0018] This utility model provides a technical solution: such as Figures 1 to 6 As shown in this embodiment, an eddy current separator for crushed scrap car materials includes an eddy current separator body 1, a conveyor belt 2 mounted on the eddy current separator body 1, and a magnetic drive device 3 disposed in the middle of the conveyor belt 2. A removal screen 4 is installed at the front end of the conveyor belt 2, and two sets of through slots 5 are provided on the removal screen 4. A fixed bracket 6 is fixed to the rear end of each set of through slots 5, and a rotary motor 7 is installed at the rear end of each fixed bracket 6. A drive seat 8 is installed at the output end of each set of rotary motors 7. Both sets of through slots 5 are... A winding rod 9 is provided, with a retainer 10 fixed to the rear end of the winding rod 9 and a rotating rod 11 fixed to the front end of the winding rod 9. Both sets of retainers 10 are inserted into two sets of drive seats 8. A movable inner cavity 12 is opened in the middle of the impurity removal screen 4. A movable block 13 is provided in the movable inner cavity 12. A pull seat 15 is fixed to the front end of the movable block 13 through a connecting rod 14. A return spring 19 is wound around the outside of the connecting rod 14. Both sides of the pull seat 15 are connected to rotating sleeves 17 through extension rods 16. Both sets of rotating sleeves 17 are sleeved on the outside of the two sets of rotating rods 11.

[0019] By installing a debris removal screen 4 at the front end of the conveyor belt 2, and installing two sets of detachable winding rods 9 inside the debris removal screen 4, the winding rods 9 can actively capture and remove debris such as ropes and plastic films, preventing blockage from the source, significantly improving sorting efficiency and continuity. Furthermore, the debris removal screen 4 is directly integrated into the front end of the conveyor belt 2, without occupying extra space. The overall equipment is compact and suitable for the transformation of existing production lines.

[0020] In other embodiments, limiting seats 18 are fixed on both sides of the front end of the impurity removal screen 4, and the two sets of extension rods 16 are located inside the two sets of limiting seats 18. This design allows the limiting seat 18 to guide and limit the extension rod 16, ensuring that the extension rod 16 will not deviate from the preset trajectory during movement. This ensures that the rotating sleeve 17 is always accurately fitted outside the rotating rod 11, maintaining the stable rotation of the winding rod 9, reducing the risk of mechanical failure, and ensuring the long-term stable operation of the impurity removal screen 4.

[0021] In other embodiments, the input terminals of both sets of rotary motors 7 are electrically connected to an external controller via wires; With this design, the rotary motor 7 is connected to an external controller via wires. The controller can precisely adjust the motor's start / stop, speed, and direction. Users can adjust the rotation speed of the winding rod 9 according to material characteristics such as impurity content and particle size to optimize the impurity removal effect, achieve remote and automated operation, reduce manual intervention, and improve production efficiency and safety.

[0022] In other embodiments, the surface of the pull base 15 is polished; This design allows the surface of the pull seat 15 to be ground, making it smooth and wear-resistant. During operation, this reduces frictional resistance with materials or other components, ensuring smooth movement of the pull seat 15 and connecting rod 14, extending the service life of the pull seat 15 and related components, and reducing maintenance frequency and costs.

[0023] In other embodiments, the diameter of the movable block 13 is the same as the inner diameter of the movable inner cavity 12, and the movable block 13 and the movable inner cavity 12 form a sliding connection; Through this design, the movable block 13 and the movable inner cavity 12 adopt a precision sliding fit, ensuring that the movable block 13 moves linearly in the cavity without shaking or deviation, and allowing the movable block 13 to rotate in the movable inner cavity 12, thereby improving the stability of equipment operation and sorting accuracy.

[0024] In other embodiments, the two ends of the return spring 19 are respectively connected to the outer wall of the movable block 13 and the inner wall of the movable inner cavity 12, and the movable block 13 is elastically connected to the inner wall of the movable inner cavity 12 through the return spring 19; This design allows the return spring 19 to continuously apply a backward elastic force to the limit seat 18, enabling the movable block 13 to quickly slip the two sets of rotating sleeves 17 onto the outside of the two sets of rotating rods 11.

[0025] This utility model provides an eddy current separator for crushed materials from scrapped automobiles, the specific working principle of which is as follows: Feeding and impurity removal stage: The crushed material first enters the impurity removal screen 4 area. The rotary motor 7 drives the winding bar 9 to rotate at high speed in the through groove 5, actively winding and removing flexible impurities such as ropes and plastic films from the material. After being wound, the impurities are rotated to the outside with the winding bar 9, preventing them from entering the sorting machine.

[0026] Material conveying and sorting stage: After impurity removal, the material falls onto the conveyor belt 2 and is conveyed to the eddy current sorting area. The magnetic drive device 3 generates a high-frequency alternating magnetic field. When non-ferrous metals such as aluminum and copper pass through, eddy currents are induced, generating a magnetic field opposite to the original magnetic field, thus being repulsed and ejected from the material flow, achieving sorting. Ferrous metals such as iron are unaffected or separated by other methods such as magnetic separation.

[0027] Adaptability and stability assurance: The movable block 13, the reset spring 19 and the limit seat 18 in the impurity removal screen 4 work together to ensure that the winding rod 9 can elastically retreat when it encounters large pieces of material or excessive impurities, avoiding jamming. The controller monitors the rotating motor 7 in real time and adjusts the speed to adapt to changes in material.

[0028] The electrical components mentioned in this article are all electrically connected to an external main controller and industrial power supply, and the main controller can be a conventional known device such as a computer that provides control.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
